STEAM- LEVER.

SPECIFICATION forming part of Letters Patent No. 252,598, dated January 24, 1882.

Application filed November 15, 1881. (No model.)

To all whom it may concern:

Be it known that I, JOHN B. COLLIN, of Altoona, county of Blair, and State of Pennsylvania, have invented new and useful Improvements in Steam-Levers; and I do hereby edeclare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This invention is specially designed for attachment to railroad turn-tables, cranes, and analogous structures for the purpose of revolving'the same; and it consists essentially in the combination of a properly-construeted locomotive with a special lever-arm, the construction being such that the power of the locomotive may be applied through the leverarm to the table for the purpose of revolving the saute without interfering at all with the capacity of the latter for balancing itselfupon its central pivot.

In the drawings, Figure 1 represents a side elevation of the lever-arm with thelocomotive and turn-table attached thereto: Fig. 2, a side elevation of the hinge-connections by means of which the lever-arm is united to the turntable; Fig. 3, a plan view of the same, and Fig. 4 a plan view of Fig. 1.

To enable others skilled in the art to make my invention, 1 will proceed to describe fully the construction of the same.

A, Figs. 1 and 4, represents a locomotive of simple type, the boiler of which and working parts attached thereto are generally located in a vertical plane, instead of a horizontal one, as is usual.

a, Fig. 1, represents a single supporting and driving wheel, held by proper bearings in line below the center of the boiler, as shown.

a, Figs. 1 and at, represents a rail extend,

ing around the pit of the table, upon which the driving-wheel of the locomotive runs.

B, Figs. 1 and 4, represents the turn-table proper, which,like all modern structures of this kind, is balanced upon a central pivot, as shown.

c 0, Figs. 1 and 4, represent two converging beams, which are united together by cross bars and braces to form a single arm, the front =end of which is supported by the journals of the driving-wheel a, and the rear end, having the hinge-plates c 0, Figs. 2 and 3, by the corresponding hinge'plates, b b, of the turn table, as shown.

By means of this construction the locomo- -tive is connected to the turn-table in such manner as to give it revolution without interfering in the least with its capacity for hal ancing itself on its central pivot. Freedom of movement in one direction is afforded by the hinge-connections by means ofwhich the turn-. table is united to the lever. and in the other by the rocking of the lever-arm upon the journals of the driving-Wheel.

The advantages of this special construction are very great. The table is left entirely free to balance itself upon its pivot'in the manner well understood. The adhesive force for the power exerted to turn the table is obtained from the weightot'the turning mechanism-i. 6., the locomotiveand not at all from the Weight of the turn-table revolved.

The invention itself may be readily applied to any turn-tables of modern construction.

This invention also may be applied not only to turn-tables, but to any similar structure, such as cranes, draw-bridges, See.

The operation will be readily understood. When it is desired to revolve the table steam is admitted into the cylinder of the locomotive in the usual manner, and the same is caused to travel on the rail and carry with it, by means of the lever B, the turn-table until the table has reached the desired position.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination with a locomotive substantially such as described, the hinged leverarm and the turn-table, as and fill the purpose set forth.

2. The locomotive A, having the single driving-wheela, in combination with the arm 0, having the hinge-comiections, and the turn-table B, as described.

This specification signed and witnessed this the 10th day of November, 1881.

JOHN B. COLLIN.
